a. d + 20

b. What don't you understand about this question?

for part a i got:d 1 20

b. how to solve and what to solve in order to get the answer

I gave you the answer for part a.

For part b --

20 + 20 = 40

etc.

a. To write an expression for the amount of money Paula withdraws if she needs d dollars, we have to take into account that she always withdraws 20 dollars more than she needs. So, the expression would be: d + 20.

b. To find the amount of money Paula withdraws for different amounts needed (d), we can substitute those values into the expression from part a.

If Paula needs 20 dollars, the expression becomes 20 + 20 = 40 dollars.

If Paula needs 60 dollars, the expression becomes 60 + 20 = 80 dollars.

If Paula needs 75 dollars, the expression becomes 75 + 20 = 95 dollars.

Therefore, Paula would withdraw 40 dollars if she needs 20 dollars, 80 dollars if she needs 60 dollars, and 95 dollars if she needs 75 dollars.
